Cerebrospinal Fluid (CSF) Protein by Electrophoresis

What Is Cerebrospinal Fluid (CSF) Protein Electrophoresis Used For?

CSF protein electrophoresis is primarily used to diagnose and monitor conditions affecting the central nervous system. It can help identify abnormal protein bands that may suggest conditions such as multiple sclerosis, infections (like meningitis), or other inflammatory or degenerative diseases of the nervous system. This test can also assist in evaluating the effectiveness of treatments for these conditions over time.

How Is This Test Performed?

A small amount of cerebrospinal fluid is collected through a procedure called a lumbar puncture (spinal tap). The fluid is then analyzed using electrophoresis, a technique that separates proteins based on their size and electrical charge. The results are displayed as bands on a gel, showing different protein types.

What Does the Test Result Mean?

The test results show the distribution of proteins in your CSF. Normal results typically show a few distinct bands, while abnormal patterns may indicate increased levels of certain proteins (like immunoglobulin bands) or unusual patterns that suggest underlying neurological issues. Your healthcare provider will interpret the results in the context of your symptoms and medical history.

Common Conditions Monitored or Diagnosed With This Test

Conditions such as multiple sclerosis, Guillain-Barré syndrome, infections (like viral or bacterial meningitis), and certain types of tumors or inflammatory diseases of the nervous system may be identified or monitored using this test. It can also help determine if treatments are working effectively.
